This data set contains the Limit of '8(g) Zone' line in ESRI shapefile format for the BOEM gulf of Mexico Region. The '8(g) Zone' lies between the Submerged Lands Act (SLA) boundary line and a line projected 3 nautical miles seaward of the SLA boundary line. Within this zone, revenues are shared with the coastal state(s). Because GIS projection and topology functions can change or generalize coordinates, these GIS files are considered to be approximate and are NOT an OFFICIAL record for the exact Submerged Lands Act Boundary.

This data set contains the Submerged Lands Act (SLA) boundary line (also known as State Seaward Boundary (SSB), or Fed State Boundary)in ESRI shapefile formats for the BOEM Gulf of Mexico Region. The SLA boundary defines the seaward limit of a state's submerged lands and the landward boundary of federally managed OCS lands. In the BOEM Gulf of Mexico Region the boundary is projected 3 nautical miles offshore from the baseline for Louisiana, Mississippi and Alabama; and 9 miles for Texas and the Gulf coast of Florida.

Spatial representations of EFH and HAPC areas as described in Amendment 1 of the Consolidated Atlantic Highly Migratory Species Fishery Management Plan based on a review of Atlantic HMS EFH. This amendment constitutes the results of the comprehensive review and update of EFH for all HMS that began with the Consolidated HMS FMP. New information, including information on the biology, distribution, habitat requirements, life history characteristics, migratory patterns, spawning, pupping, and nursery areas of Atlantic HMS were taken into consideration when updating EFH in this amendment.

This data set is a subset of the digital hydrologic unit boundary layer of the Watershed (10-digit) 5th level for the states bordering the Gulf of Mexico. This data set was derived from the nation-wide hydrologic unit boundary layer produced by the Natural Resources Conservation Service of the U.S. Department of Agriculture.

This data set is a subset of the digital hydrologic unit boundary layer of the Subwatershed (12-digit) 6th level for the states bordering the Gulf of Mexico. This data set was derived from the nation-wide hydrologic unit boundary layer produced by the Natural Resources Conservation Service of the U.S. Department of Agriculture.

This data set is a subset of the digital hydrologic unit boundary layer of the Subbasin (8-digit) 4th level for the states bordering the Gulf of Mexico. This data set was derived from the nation-wide hydrologic unit boundary layer produced by the Natural Resources Conservation Service of the U.S. Department of Agriculture.

This hurricane dataset is a 10 minute grid based on a subset of the 1851 - 2012 hurricane tracks from the International Best Track Archive for Climate Stewardship (IBTrACS) and the National Hurricane Center. The grid has attributes added that allow analysis of hurricane frequency in the Gulf of Mexico. The grid only references systems that were Tropical Storm strength or greater. Only tracks that entered the Gulf of Mexico are included. (For example, storms that moved westward across Florida, but did not emerge into the Gulf, were excluded.)

These data represent the geographic area described in Title 50 CFR Part 622.34(a)(1), Fisheries of the Caribbean, Gulf of Mexico, and South Atlantic, Subpart B - Reef Fish Resources of the Gulf of Mexico, Seasonal and area closures designed to protect Gulf reef fish, Closure provisions applicable to the Madison and Swanson sites, and Steamboat Lumps, and the Edges, as of 07/01/13.

This GIS data set represents mangroves in Florida. The data are reselected from land use and land cover data from Florida's water management districts.

The map depicts the distribution and extent of mangroves coverage in Mexico using SPOT 5 satellite imagery.
